Subcontracted employees at the Philadelphia International Airport will on Monday announce the filing of numerous federal complaints alleging safety hazards.

Employees of the Philadelphia International Airport will gather at City Hall on Monday morning with disability rights advocates, officials with property services union 32 BJ and members of City Council to announce the filing of numerous complaints with the U.S. Occupational Safety and Health Administration and the U.S. Department of Transportation.

The workers' allegations include exposure to bodily fluids, a lack of required training, and potentially hazardous conditions for wheelchair operators and passengers at the airport.

The subcontracted employees – many of whom make just the federal minimum wage and receive no benefits – have rallied in the past for better working conditions, winning the support of unions and religious coalitions.

Philadelphia International Airport workers and activists will announce the alleged safety violations in detail at the meeting.
